Abstract

Rate constants for the collisional excitation of CO by para-hydrogen are calculated in the temperature range 5 <= T <= 2000K using the coupled states approximaton and a recently determined new potential surface. The results differ appreciably at high temperatures and large Deltaj transitions from those recently used in the interpretation of shock wave models in molecular clouds.
